Hangman
Two games on one gallows. In 看图猜字 a picture comes up and you pick its characters from the tiles; in 中译英 a Chinese word comes up and you spell its English one letter at a time. Every miss adds a piece to the little figure — six pieces and the word is lost, the word is read aloud, and the next one comes. Pick a level and a topic; put it on the projector and let the class call the letters.
Pictures and words take turns — every next word switches game where it can.

Words are graded against the HSK 3.0 word list; pictures are drawn in the site's clay style; the Chinese is read in the teacher's voice where a recording exists, and by the browser's voice where not. Nothing is stored beyond your own settings on this device.
